Question

Write equations for the following number pattern.

x y
1 -2
4 -5
7 -8
10 -11
13 -14

Answer 1

Multiply x by -1 and subtract 1

Answer 2

You are working on linear equations aren't you?

Answer 3

but you had that right answer thanks!

Answer 4

But don't you want to know how to find the answer?

Answer 5

yeah I do

Answer 6

we know that equations of lines look like this: y = mx + b. So we need to find the slope. We can do that by looking at the number pairs we have. In this example, I saw that the y value went down 3 while the x value went up 3. That was -3/3=-1. So I multiplied the x by -1 and figured out what I had to add to get y and that gave me my rule.

Answer 7

ok, thanks
